. One object of my present invention is to pro,- duce 'a machine which will act to automatically treat cakes of filaments so that their wet-treatment is facilitated. Y t I ,5 4 to present a machine which skeins of the same. 7 M

Other objects will become, apparent from a reading of the following specification and a 'study' of the accompanying drawings, in which: Figure I is a side elevational view'of my im- 1 provedapparatus. I,

1 Figure II is an end elevation of the same.

Figures III, IV, V and VI are detailed views of the actuating elements later to be described,

- In the production of articial filaments by the v pot-spinning method, a cellulosic solution (cellu losexxanthate; cuprammonium cellulose,'etc.) is made up, and after proper preliminary treatment is extruded or expressed through minute openings into a setting or coagulating medium, The

filaments are then led over proper guides-"into acentrifugally spinning container or'pot," where they are collected in the form of a cake of twisted filaments. The cake is then after-treated or-wettreated so as to wash, bleach, etc, the filaments such cakes/and a new method for treating the same. 1" I v When filaments are'produced by the viscose or cellulose. xanthate method, it. is necessaryto desizethe filaments in the wet treatmentthereof; This wet-treatment maybe accomplished by arranging skeins ofthe filaments in rows under a dripping apparatus, andallowing the, treating sults are accomplished. Mynew; device automaticallymovescakes of filaments to thedripthem together at the sides. 1

treating arrangement and whilev so moving them changes them to the form of skeins by pressing My device consists essentially of a fixed frame (1) supporting transporting rails (3) and (4). The cakes of filaments (C) are arranged on sticks (2) and arranged in rows upon the transporting means (3) and (4). the sticks (2) and the cakes (C) isacco'mplished. by the :reciprocal motion of the movable rails' The movement of (3) and the fixed rails (4). Arranged within .the fixed frames (1) there is a movable frame (5) towhich'the rail (3) is attached; This niovable frame (5) is actuated by the crank-like arrangement (6) Through motion of the cranks (6), the carrier frame (5) is put in motion so,

, that it describes a circularmotion lying in the longitudinal plane of the entiremachine.

Notches (n) (Figures 111 through v1) are pro I vided so that they are situated at such a position that the sticks (2) are engaged after each cycle of, rotation of the movable rod '(3). By the use of these notchesythe movablerail portion describes a circle, actuated by means ofthe crank (6); throughthe movable frame (5) and lifts the sticks.-, As the circleisnearly completed, the sticks or rails (2), are ;loos'ened andli'e in the notches (n) until grasped by the next lsucceeding portion"(3) in its circular movement. This moves the sticks'or rails progressivelyalong'the I frame. "The sticks,"thusprogressing, carrythe cakes through the gripping means for compress ing them into a skein-like form, and to the end portionofthe machine where they may be treated by the drip treatment method described above. 'Iheactual gripping arrangement provided for v the formation" of the skein-likegroupsbf -fila ments is set forth in" Figures III. through-VI." In Figure I, I have shown how the frame "portion (1) "is provided with a holding arrangement or rod (7)"-where'at -the fixed point (8) the plates 3 (9) and (10) are attached. These latter are" 8 shown in detail infthe last' fou'rrfigures'of the ydrawings.- These plates (9), and (10)'*are moved," f r respectively by the actuating'rods (12)/and.(1'1),

which'are pivotally connected to the movable I frame (3) 'Ascan be I seen froma study onne drawings, this combination of 'frames with vco'mmon jointsqand a fixed frame, on the one hand, and the rods (11) andv (12) with the movable frame (3) *onthefother hand act sothatthe" v v a 951 closed, or moved to and from one another, by

pairs of plates (9) and (10) are opened "and the rotatingmovement of the movable carrier frame. Through the opening and closing 'of these frames;(9) and (10) the spinning cakes as they pass are gripped and compressed to a'certain' e'x- 190 tent, thus producing a skein-like formation (S). The, pressing plates (9) and (10) .may consist of oblong wide boards-which extend over the entire length of a whole row of spinning cakes,

or, as an alternative, the pairs of plates which 105 operate together may be connected to the pairs of plates located on each side of the arrange ment and situated so as to press the cakes on one of the rods at a single time.

In the disclosed arrangement Ihave provided 110 wet-treatment device maybe combined with the means'whereby the sticks or rods carrying the cakes progress for a greater'distance when the filaments are in the form'of cakes, and during their transformation into skeins than afterwards when they are in skein form. In order to accomplish this, the levers 13) and (14) have been are run.

provided, which levers move upon the bolts (15) and (16) of themovablerail (3). The levers (13) and (14) are provided with slots (17) and (18) in which the steering bolts (19) v and (20) These two bolts (19) and (20) are themselves connected to the' fixed rail portion (4). (3) and (4) the levers (13) attached to both sides of the machine seize with their upper jaws or portions the washing sticks (2) with the cakes (C), lift them'up (Figure IV), carry them just below the pressing plates (Figure V), where they are pressed together in the manner indicated above).

(Figure VI.) During'the same operation, and in ,a similar manner, the levers (14) seize the just folded cakeslying under the pressingplates (Figure III), lift them, (Figure IV), and carry them; to the grooves placed at the right -of the arrangement (Figures ,V and VI) The operation 7 for the pressing by the plates (9) and (10) takes placecorrespondingly and simultaneously with the advancing of the sticks and cakes by the levers. As indicated in Figure III, the plates (9) and (10) open to clearthe way, and according to Figure IV the already folded cake may be advanced and the next cake to be pressedbrought under the plates. Figure V shows the plates just as they are advancing towards the cake to press it into theform shown in Figure VI.

el have shown several'grooves placed before'the portionof the arrangement where the gripping platesf (9) and (10) operate, but these'are provided for'the purpose of having a reserve=of the sticks and cakes onha'nd tofacilitate the con tinuous operation of the'machine.

.After being thus handled, the sticks contain- I ing the. yarn may ,be transportedto, some other location for the wet-treatment process, or, as indicat'ed'by Figure II-(right-hand portion)- a machineitself H In "certain cases it may be found convenient or necessary; to moisten the spinning cakes-before they arespre'ssed together, and for this-purpose )Ixhave provided dripping grooves (22).

' In some instanceslit is found advisable to so arrange the gripping plates (9) and (10) that indicated by they donot press the cakes together too far. 7 If theyjare pressed too close together, they tend to grip'the carrying stick (2) and so'imp'ede the working thereof. In order to adjust the plates, the push bars (11) and (12) may be arranged in a suitable position, or the bolts between the pressing plates (9). and (10) may be adjusted. One 'means for providing for such an adjustment is the slots (a) and (b) in"(11) and,

'The various .machineparts which come into Upon the reciprocal motion of the rails contact with the treating liquid may be made of some suitable matter which is resistant thereto.

The pressing plates may be made of hard rubber or bakelite, or may be covered by the material of which the rest of the frames is composed. Having now set forth my invention as required by the patent statutes, what I wish to claim is:
